Application filed August 1, 1908. Serial No. 446.41%.

T all whom it may concern: is given a suitable angle to conform it to the Be it known that I, CnAnLEs EDWARD handle of the saw. It is provided near its LOWE, a citizen of the United States, and a bottom with a hole 0 communicating with resident of Mciilester, Pittsburg county, Okthe interior of the lubricator and affording an lahoma, have invented new and useful Imexit for the oil. T his hole is above and prefprovements in Lubricators for Handsaws, of erably in line with the saw blade. The )late which the following is a full, clear, and exact 1) extends below the lubricator forming a ipf. specification. In the center of the lip is a slit 9 into which lily invention relates to lubricators for fits the blade of the saw and per its the lip f 10 handsaws and is designed to lit within a to extend downward for a suitable distance chamber formed in the handle of the saw from on either side of the blade. On either side of which position it is operated to lubricate the the slit g grooves h-Jt are formed extending saw blade. from the edge of the lip to the hole 6. These Referring; to the drawings forming part of aid in feeding the oil coming from the lubrithis specification, Figure 1 shows a saw cater to both sides of the blade at the same equipped with my lubricator, the recessed time. portion of the handle being shown in section At the upper end of the plate 7) is a depresand the lubricator being broken away to sion 'L and midway on the plate are lu s show a part of the interior.

The exposed face of this of) tance through the handle but without mateplug fits snugly upon the hole to close it and 8.3 rially weakening the handle when forming hold back the oil when not needed. This is the retaining chamber. a simple and effective method of closing; the The lubricator may be made of sheet metal outlet but many other methods may do as or may be cast.

To retain the lubrlcator in secured respectively. posltion within the saw handle a facing plate A chamber B is mortised in the handle C of E is used. This has an open slot 7 cut in it, the saw D into which the lubricator is snugly thus forming the two prongs s s which are 40 fitted. The lubricator may if desired be cyslid into the grooves qq from the top there- 5 lindrical and a hole may be bored in the hanof downy ard. Screw holes t-t are prodle to receive it, but a rectangular recess in vided in the top and bottom of the plate E most cases is preferable as it gives a large for screwing it to the saw handle.

The front of the lubricator may and resilient as where sheet metal is used, be made integral with the sides or it may be the flow of the oil may be increased by pushmade separate as where sheet metal is used ing the side in when the outlet is opened, in so for the sides. The front may be soldered to the usual way that oil cans are operated.

the sides or secured by any of the other well To accomplish this, a hole is made in one side known means. of the lubricator and is reinforced by the W here the front plate I; is made separate it flanged ring 11 having an internal screw is best provided with a flange d for better sethread. A hole to is made in the handle to 55 curing it to the lubricator sides. The plate I) register with this opening to permit a screw 9: 11

to be screwed therein. This opening also affords an easy way of refilling the lubricator when necessary. l' fhere the chamber to retain the lubricator is inortised entirely through the handle, then a facing plate y should be screwed on to the handle to cover the opened end of the chamber.

My lubricator is easily installed in a sav handle after the mortise is made. The plate E is first slipped in place within the grooves qg and the lubricator pushed into the handle, the rounded end 0 helping in inserting it. The plate E is then screwed on to the handle to secure the lubricator in place. It is then filled through the side opening and the screw a screwed in. t is best to use a soft washer on the screw to make a tight joint. lVhen it is desired to oil the saw the thumb end of the lever is pushed in, This raises the other end and opens the lubricator. The oil then flows down both sides of the blade and may be spread around by the hand if necesssary. Then the pressure is removed from the lever the spring reacts, and the plug 79 securely closes the hole.

Where the lighter oils are used, such as kerosene, it may not be found necessary to force in the side of the lubricator to increase the flow, except where the opening is made small and a quick flow is desired. But where the heavier oils are used, pushing in the side by means of the screw plug a will aid materially in forcii'ig a flow against the atmospheric pressure.

Having thus described my invention I claim 1. Alubricator for a hand saw comprising a reservoir adapted to fit wholly within a cham ber formed in the handle beyond the end of the blade and transversely thereto and having an exposed face beneath the handle when inserted, an opening in the said face to emit the oil and means for closing the opening when the flow of oil is not desired.

2. A lubricator for a hand saw adapted to fit within a chamber formed in the handle and having an exposed face when inserted, a hole in the face to emit the oil, a lever secured to the face, one end of said lever adapted to close the hole in the face, the lever being adapted to be operated at the other end to effect a raising and lowering of the first end from and over the said opening respectively toeifect an opening and closing of the hole.

3. A lubricator for a hand saw adapted to fit within a chamber formed in the handle and having an exposed face when inserted, an opening in the face near the bottom to emit the oil, a depression formed near the top, a pair of lugs formed on the plate be tween the hole and depression, a lever pivoted to said lugs, one end of'said lever adapted to cover the hole, the other end having a pinprojecting from its back, a spring mounted on said pin and seated in said depression, forcing the said end of the lever upward operating it to bring the first end down in spring pressed engagement over the hole to close it, and means for securing the lubricator in position.

4. A hibricator for a hand saw adapted to fit within a chamber formed in the handle and having an exposed face when inserted, an opening in the face near the bottom to emit the oil, a depression formed near the top, a pair of lugs formed on the plate between the hole and depression, a lever pivoted to said lugs, one end of said lever faced with a pliable material to adapt it to cover the hole, the other end having a pin projecting from its back, a spring mounted on said pin and seated in said depression forcing the end of the lever upward operating it to close the hole at the other end, means for securing the lubricator in position, a screwthreaded hole formed in one side of the lubricator,;-for filling the lubricator, a screw plug to close said hole extending through a corresponding hole in the handle and serving also as a thumb piece to force the side of the lubricator in when made flexible to aid in ejecting the oil.

5. A lubricator for a hand saw adapted to fit within a chamber formed in the handle and having an exposed face when inserted, an opening in the face near the bottom to emit the oil, a depression formed near the top, a pair of lugs formed on the plate be tween the hole and depresssion, a lever pivoted to said lugs, one end of said lever faced with a pliable material to adapt it to cover the hole and the other end having a pin projecting from its back, a spring mounted on said pin and seated in said depression forcing the end of the lever upward. operating it to close the hole at the other end, a locking plate fitting in grooves formed in the side of the said exposed face and provided with screw holes for securing it to the saw handle, a screwthreaded hole formed in oneside of the lubricator, for filling the lubricator, a screw plug to close said hole extending through a corresponding hole in the handle and serving also as a thumb piece to force the side of the lubricator in when made flexible to aid in ejecting the oil.
